Genetics Review

Some genes are located close together on a chromosome and often inhereted together. This inheritance pattern is called:

• Codominance

• Linked Traits

• Sex-Linked Traits

• Multiple Alleles

In order for a mutation to be passed on from parent to offspring, the mutation must occur in:

• Somatic Cells

• Gametes

• Brain Cells

• Any Cell of the Body

For an XX female to express a recessive sex-linked trait, she must have:

• a Y chromosome

• 1 recessive allele

• 2 recessive alleles

• 2 dominant alleles

The sugar in DNA is:

• Dioxyribose

• Ribose

• Glucose

• Lactose

On a pedigree, a female is represented by:

• Circle

• Square

• Triangle

• Octogon

Which cells are NOT formed during meiosis?

• Somatic Cells

• Gametes

• Sex Cells

• Sperm Cells

A cell that is HAPLOID has

• The same number of chromosomes as the parent cell.

• Half of the number of chromosomes of the parent cell.

• Twice as many chromosomes as the parent cell.

• I have no ides what haploid means.

How many chromosomes are in a human egg cell?

• 12

• 23

• 46

• 97

What is the purpose of mitosis?

• Create gametes

• Build and repair tissues

An example of a heterozygous genotype is:

• bb

• RR

• brown hair

• Ff
